SMELTING-FURNACE.

Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed August 17, 1908, Serial No. 448,854. Renewed August 27, 1909. Serial No. 514,878.

To all whom it may concern:

Be it known that I, MIRKO Hiiino, a subject of the Emperor of rrustria-I-Iungary, and resident of Collinsville, Illinois, have invented certain new and useful Improvements in Smelting-Furnaces, of which the following is a specification.

My invention relates to improvements in smelting furnaces and has for its object to provide a furnace in which the ore to be smelted is subjected at all of the stages of its reduction, to the heat generated by downdraft furnaces, and in which the metal freed from the ore by the action of the heat is twice strained through perforated surfaces; the further objects of the invention and its results being hereinafter more fully described.

In the drawings-Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical, longitudinal view in section of the same, taken along the line 3-3 of Fig. 2. Fig. 4 is a transverse sectional view of the same taken along the line 4-4 of Fig. 3. Fig. 5 is a similar view in section, taken along the line 5-5 of Fig. 3. Fig. 6 is a transverse, vertical view in section of the same, taken along the line 6-6 of Fig. 1. Fig. 7 is a front elevation of the same.

The heat desired to be used in the device of my invention is generated in the fire-box 8 which is provided with the side openings 9-9 provided with the doors 10-10; the fire-box8 also having the front opening 11 provided with the door 12, and being provided at its bottom with the grate bars 13. The fire-box 8 is provided with the rear wall, of fire-brick or the like, 14, shown in section in Fi 3, over which the products of combustion from the fire-box 8 pass, and then pass through the oven 15.

The oven 15 is provided with the bottom 16 having at its front end the retaining wall 17 and at its rear the retaining Wall 18'; the bottom 16 being provided with the erforations 19 and being constructed of reclay as are also the walls 17 and 18. The bottom 16 is preferably concave as illustrated in Fig. 6. Beneath the bottom 16 the perforated pan or strainer 20 is slidably mounted; the perforations being indicated in Fig. 3 by the numeral 21; the straining member 21 having the side flanges 22, front flanges 23 and rear flanges 24. When the straining member 20 is in place, the rear wall 25 is ing downwardly through and from the rear wall 31 I provide the pipes 32, which pass through the doors 26-26, said doors 26-26 being perforated to admit the passage of said pipes 32-32, as indicated by the numeral Beneath the container 27, the furnace of my invention is provided with the staggered partition walls 34, 35, 36 and 37, arranged as shown in Fig. 5, which are designed to form a flue for the outward passage of the products of combustion, in the direction indicated by the arrow in Fig. 3; the top of said flue being formed by the imporforate bottom 28 of the container 27 and the bottom of said flue being formed by the baseplate 38 with which the furnace is provided; the flue so formed being indicated by the numeral 39. The flue 39 in turn communicates with the line 40 formed as shown in section in Fig. 3 and extending outwardly to a point beyond the ash-box 41. The ashbox 41 is provided with the front opening 42 and door 43.

The oven 15 is provided with the side openings 44-44 which in turn are provided with vertical sliding doors 45. The space between the oven bottom 16 and the straining pan 20 (indicated in Fig. 3 by the numeral 46) is also provided with side openings 47-47, which in turn are provided with sliding doors 48. The doors 45-45 are suspended by cords 49 passing over pulleys 50-50 and 51-51, the depending end of the cords 49-49 passing into the tubular.

guides 52-52, and the lower ends of said cords 49-49 being provided with weights 53-53. A like means of support is provided for the doors 48-48; these doors being provided with brackets 54-54, to the outer ends of which are attached the cords 55-55 passing over the pulleys 56-56 and provided at their outer ends with the weights 57, which weights are also contained in the guides 52 at one side of the doors 48, and 58 at the opposite side of said doors 48. The doors are hinged as indicated by the numeral 59 and provided with cords 60 passing over pulleys 61 and 62 and having weights 63 operating in the vertical guides 64.

The mode of operation of the device of my invention is as follows. The ore being placed in the oven 15, the metal freed from the ore by the action of heat from the firebox 8 passes downwardly through the perforations 19 into the straining member QO QO. It is then further freed from impurities by passing through the perforations 21 into the container 27. The outer ends of pipes 32 are plugged with clay in the manner usual to the art during the accumulation of the molten metal in the container 27. \Vhen the desired amount of metal has accumulated in said container 27, the pipes 82 are tapped by the removal of the fire-clay from their mouths and the free metal is drawn away to be cast in such forms as may be desired.

The top wall of the furnace 65 is provided with fire-proof material 66 and the doors 2626 are similarly provided as indicated by the numeral 67. Similarly the front wall 68 is provided with fire-proof material as indicated by the numeral 69 and the side walls 70-70 are similarly fire-proofed as indicated by the numeral 71. The doors 1010 are provided with a lining of like fire-proof material as indicated by the numeral 72 and the doors 45 and 48 are similarly lined with fireproof material as inclicated by the numeral 73. The removable fire-proof wall is supported by the removable transverse bar 74:, and the side walls are connected by tie-bars 7 5.

Having thus fully described my invention, what I claim as new and desire to have secured to me by the grant of Letters Patent, is:

In a smelting furnace, a fire-box; an oven having a perforate bottom; a straining member mounted beneath said oven; a con tainer mounted beneath said straining member; a flue extending downwardly from the oven; a second flue communicating therewith and extending beneath the container; and another flue communicating with the last named flue and passing beneath the firebox to the exterior of the furnace, substantially as described.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.

MIRKO HIKEC.
